Recommendations
It is recommended to use CBCT’s as mentioned in the table, to ensure the trip
current accuracy.
Caution
1. Always follow instructions stated in this quick start manual.
2.Before installation, ensure that specications compatible with intended
application.
3.Installation must be done by a successful electrician.
4.Suitable dampers must be provided in case of over-vibration during installation.
5.Automation and control devices must be installed so
that they are protected against any risk of involuntary
actuation.
6.Disconnect the power before working on the device.
Terminal Details
Use Cu Wire of 60/75°C only
Notes
1. Since the innovation of the product is a regular process, we reserve the right
to change all its features without prior notice.
2. The factory settings of the device are set to 30mA trip and instantaneous
delay.
These settings can be adjusted as needed by the installation. A seal is supplied
allowing the user to secure the clear window and hence prevent any unnecessary
adjustment of the settings.
3. To comply with regulations, it is recommended that the device should be
tested periodically to ensure correct operation.
4. In case of excess harmonics power transmission cables have more leakage
because of low impedance oered by cable capacitance, IΔn setting need to
keep at higher level.

Trip Characteristics
Standard IEC 60947-2 annex M indicates the operating characteristic for a
nontime-delay type in table B.1 in B.4.2.4.1 in standard IEC 60947-2 annex M.
CBRs having I∆n = 30 mA shall be of the non-time-delay type.
If the trip time is set at ‘0’ sec, then for 5 I∆n & 10 I∆n, the tripping time will be
< 40 ms for all current ranges.
